If you have ever bought something from an online marketplace and wondered who is responsible when it turns out to be fake, unsafe or nothing like the photo, you are asking the question the European Union tried to answer with the Digital Services Act, often shortened to DSA. It applies across the EU and touches services people elsewhere use too, because global platforms tend to apply changes widely.
This explainer covers what the law is, how it affects online shopping, and what you can do as a consumer. It is not legal advice, and it does not discuss any specific investigation.
What the Digital Services Act is
The Digital Services Act is an EU regulation that sets rules for online intermediaries: social networks, search engines, app stores and marketplaces. The central idea is that what is illegal offline should also be illegal online, and platforms must have processes to deal with illegal content and unsafe products. Obligations scale with size.
The law distinguishes small services from very large online platforms, which are those reaching a very large share of EU users. The largest face the strictest duties, including risk assessments, independent audits and data access for researchers. Regulators, including the European Commission for the biggest platforms, can request information, open investigations and impose fines for breaches. For the official background, see the page on the Digital Services Act.
What the Digital Services Act requires of marketplaces
For shoppers, several rules matter most.
Notice and action. There must be a clear way to flag illegal items or content, and the platform is expected to act diligently on reports.
Trader traceability. Marketplaces must collect and check basic information about the businesses selling on them, which makes it harder for rogue sellers to hide behind anonymous accounts.
Advertising transparency. Users should be told that something is an ad, who paid for it, and the main reasons they are seeing it. Targeting ads based on sensitive personal traits is restricted, and ads aimed at minors using profiling are prohibited.
Clearer recommendations. Platforms must explain the main parameters of recommendation systems in their terms, and the largest ones must offer at least one option not based on profiling. This sits alongside the practices we describe in how product recommendations work in online stores.
No dark patterns. Interfaces should not trick people into choices, such as by hiding the cancel button.
What changes for you as a shopper
In practice, you should find it easier to report a bad listing, see who really sells a product, and understand why a platform shows you what it shows. If a platform removes your content or closes your account, it generally has to explain why and offer a way to challenge the decision, including out-of-court dispute settlement bodies in the EU.
The Digital Services Act does not guarantee that every product is safe, and it does not turn marketplaces into the seller. Consumer protection rules for product safety, returns and warranties still apply separately. What it adds is a framework for faster removal, better traceability and more accountability.
A short example
Say you order a children’s toy from a third-party seller on a large marketplace, and it arrives with sharp edges and no safety markings. Under the Digital Services Act framework, you can use the reporting tool to flag the listing, and the platform is expected to review the notice and act. Because it has had to collect details about the trader, authorities and other buyers have a better chance of identifying who is responsible. You should still use your usual consumer rights to ask for a refund. The two systems work side by side, one for removal of the product and the other for your money back.
Practical tips for buying online
- Check who the seller is. Look for a business name and contact details on the listing. Missing information is a warning.
- Use the report tools. If a listing looks fake or dangerous, flag it. Reports are how platforms spot patterns.
- Be wary of extreme prices. A deal that looks too good often is.
- Pay through protected methods. Card payments and established wallets usually offer dispute routes.
- Save evidence. Keep screenshots, order confirmations and messages in case of a dispute.
- Read the ad labels. Sponsored results are not necessarily the best ones.

Why people outside the EU should care
Companies often find it simpler to build one system than many. Features such as reporting tools, ad labels and seller verification may therefore appear in other regions. Other governments are also watching, and some are drafting their own online safety laws, so the Digital Services Act has become a reference point in global debates about platform responsibility.
There are criticisms too. Some worry about the burden on small companies, some about how consistently the rules are enforced across countries, and some about the risk of over-removal of legitimate content. Those debates are ongoing, and the law will be tested through real cases for years.
Looking ahead, rules like the Digital Services Act will probably keep evolving as regulators learn what works. Expect more guidance, more court decisions and more detailed reporting from platforms. For shoppers, the practical effect should be small improvements you notice gradually: clearer labels, easier complaints and fewer anonymous sellers.
The short version for shoppers: the Digital Services Act gives you more visibility and more ways to complain, not a guarantee. Combine it with good habits, check the seller, and treat the new tools as a safety net rather than a promise that nothing can go wrong.
